Description
I have some code here: https://github.com/ariovistus/esprima-bug
test.js uses esprima 4.0.1 to parse tok.js and outputs
define "urijs" 2250,2265
which is the position of the last part of tok.js, define("urijs"), as reported by esprima. but it is wrong, the actual position should be 2272

Research direction
Start by running test.js from the linked ariovistus/esprima-bug reproduction against esprima 4.0.1 and comparing the reported range for tok.js with the actual source position. Trace how the parser computes the range for the final define("urijs") segment, then verify the result is 2272 and preserve the case in a regression test.
